Jacie can swim 3/4 of a mile in 3/8 of an hour. how far can she swim in one hour?

2 miles

Step-by-step explanation:

We can use ratios to solve this problem

3/4 miles         x miles

=

3/8 hours          1 hours

Using cross products

3/4 * 1 = 3/8 * x

Multiply by 8/3 to isolate x

3/4 * 8/3 = 3/8*8/3 *x

8/4 = x

2 =x

pls ask

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,
